One of the key components to any injection molding operation is the sprue bushing. The center hole (sprue) allows for material flow from the injection nozzle to the runner system. The sprue bushing is flush mounted to the clamp plate and ensures the positive alignment and seal needed between the sprue and the injection nozzle. JBF National sprue bushings are manufactured from steel with a through hardness of 43/45 RC and have been designed and tested to operate consistently under the most strenuous situations.

Do you need to secure two pieces of work without creating a permanent connection like a weld? If so a button handle quick release pin could be exactly what you need. The ball locking action these pins feature provide positive engagement until the button is depressed by the operator, thereby allowing for quick disengagement. Stainless steel construction ensures effortless sliding action time after time, as well as protection from corrosion.

How do you effectively apply a high amount of torque when needed? By using a 4-prong stainless steel hand knob. Due to their extended prongs and their enlarged surface area, 4-prong hand knobs offer maximum finger and palm engagement therefore allowing for highest amount of force application. The stainless steel design of this clamping knob ensures reliability, and makes it ideal for situations with sanitation and cleanliness concerns, while retaining an eye pleasing finish.

From single prototype to large volume production runs with design intricacies ranging from simplistic to highly sophisticated, JBF National can handle it.

Ball and spring plungers (also known as “spring loaded devices”) at their very basic, are indexing and positioning devices that allow for quick and reliable alignment between various objects, while allowing for quick disengagement. Their enclosed bodies ensure that the spring and nose stay in place, thereby ensuring consistent and reliable pressure application.
